Question

我正在研究网络应用项目。我有文件上传的问题。它适用于管理员，但对于常规用户文件不保存。 mu views.py 或模板html

一定是个问题

forms.py

class DocumentUpload(forms.ModelForm):
    class Meta:
        model = Form
        fields = ('file',)

models.py

class Form(TimeStampedModel, TitleSlugDescriptionModel):
    author = models.ForeignKey(User, on_delete=models.CASCADE)
    title = models.CharField(max_length=512)
    is_final = models.BooleanField(default=False)
    is_public = models.BooleanField(default=False)
    is_result_public = models.BooleanField(default=False)
    file = models.FileField(null=True, blank=True)

    def __str__(self):
        return self.title

    def get_absolute_url(self):
        return reverse('form-detail', kwargs={'slug': self.slug})

views.py

def create_form(request):
    if request.method == 'POST':
        user = request.user
        data = ParseRequest(request.POST)
        print(data.questions())
        print(data.form())
        parsed_form = data.form()
        parsed_questions = data.questions()

        # tworzy formularz o podanych parametrach
        formfile = DocumentUpload(request.POST, request.FILES or None)
        if formfile.is_valid():
            form = formfile.save(commit=False)
            print(form)
            form.author = user
            form.title = parsed_form['title']
            form.is_final = parsed_form['is_final']
            form.is_result_public = parsed_form['is_result_public']
            form.description = parsed_form['description']
            form.save()
            # zapisuje pytania z ankiety wraz z odpowienimi pytaniami
            for d in parsed_questions:
                question = Question(form=form, question=d['question'])
                question.save()
                # dla kazdego pytania zapisz wszystkie opcje odpowiadania
                for opt in d['options']:
                    option = Option(question=question, option=opt)
                    option.save()
            return render(request, 'forms/form_form.html', {})
    else:
        form = DocumentUpload()
        return render(request, 'forms/form_form.html', {'form': form})

create_form.html

    {% block content %}
    <form method="post" id="form" enctype='multipart/form-data'>
    {%csrf_token %}
    <div class="form-group">
         {% csrf_token %}
         <label for="form-title">Tytuł formularza</label>
         <input id="form-title" class="form-control" type="text" 
                                  placeholder="Tytuł" required/>
     </div>
        {{ form.as_p }}
    <input class="btn btn-default" type="submit" value="zapisz"/>
    </form>
    {% endblock %}

5的 settings.py

....
DATABASES = {
    'default': {
    'ENGINE': 'django.db.backends.sqlite3',
   'NAME': os.path.join(BASE_DIR, 'db.sqlite3'),
    }
}
STATIC_URL = '/static/'
STATICFILES_DIRS = [
    os.path.join(BASE_DIR, 'static'),
]
MEDIA_URL = '/media/'
MEDIA_ROOT = os.path.join(BASE_DIR, 'media')

STATIC_ROOT = os.path.join(BASE_DIR, 'static')
...

5的 urls.py

if settings.DEBUG:
    urlpatterns += 
     static(settings.STATIC_URL,document_root=settings.STATIC_ROOT)
    urlpatterns += static(settings.MEDIA_URL, 
         document_root=settings.MEDIA_ROOT)

Answer 1

您忘了在action添加form，就像这样：

<form action="{% url 'name_of_your_function' %}" method="post" id="form" enctype='multipart/form-data'>
...
</form>

操作必须包含您的网址名称，例如：

url(url_regex, views.function, name="name_of_your_function"),

Answer 2

您尚未在upload_to中为FileField指定models.py属性。

为您的字段添加目录，例如

file = models.FileField(upload_to='uploads/', null=True, blank=True)

您的表单一切正常，文件已通过请求发送，但Django不知道保存文件的位置，直到您在模型中定义它。
